Advice Me: I Am Sleeping With My Brother’s Wife And She Doesn’t Want It To Stop

I am a man of 26 years old and I started living with my brother about four years back when I first came to Lagos. He was unmarried as of when I first came from Abuja but he got married later on and I still kept on staying with him. I don’t know how to explain it but somehow because his wife is a full time housewife and I don’t have a job yet, we always get to be at home alone most of the time. I can’t remember how it started but we have been having sex for like a year now.

My brother has been very good and I feel bad that I am sleeping with his wife. The woman in question is very beautiful and she has threatened that if I tell my brother or stop the affair, she is going to make sure that I regret it for the rest of my life. I don’t know what to do because I don’t know how my brother would react if he finds out that I am sleeping with his wife. If he throws me out, I have nowhere to go and I don’t have money to my name, at the same time I don’t think I want to go on with this affair with his wife.

Please people advice me, what can I do?
